•
•
•
•
16 SPDT relays with 120-volt/1A rating,
On-board relay driver circuits,
LED indicators to monitor relay activity,
Single +5-volt power supply,

MR16 DESCRIPTION
Board Settings
The MR16 board has jumper settings you can change if necessary for your application. The factory settings are
listed in this section. Should you need to change these settings, use these easy-to-follow instructions. Figure 1 shows
the board layout.
Fig. 1 — MR16 Board Layout

P3 — Internal/External Power Source, +5 Volts (Factory Setting: +5V INT.)
Header connector P3, shown in Figure 2, let you select the power source for the MR16. Each relay consumes
about 33 mA when energized, so the maximum current requirement for all relays energized simultaneously is about
0.53 A. Taking this much current from the computer’s +5 volt power bus could overload the PC’s supply if you
have other circuitry drawing high current (such as two or three MR16 boards daisy chained). P3 can be used to
jumper to an external +5 volt power supply. The external power sources are connected to the MR16 board at TB4,
located to the left of P3.

P5 Through P20 — Bypass/Normal Relay Operation (Factory Setting: NOR (Normal))
Header connectors P5 through P20 (P5 is shown in Figure 3) let you bypass an individual relay so that the
digital output line can be brought out to the external I/O connector where it can be used for digital control functions.
The jumper for each relay channel is factory installed across the NOR pins for normal relay operation (the digital
output line controls the relay). To bypass the relay, move the jumper to the BYP pins and install a 0 ohm resistor (or
jumper wire) in the corresponding resistor pads. R1 is the Channel 1 resistor pad, R2 is Channel 2, and so on
through R16, as marked on the board. Note that you must move the jumper to BYP and install a 0 ohm resistor to
bypass the relay. The relay channel diagram on page 6 shows this circuitry.

Connecting to the PC Interface Board
Connecting to a 50-pin Interface Board
Figure 4 shows the MR16’s P1 I/O connector pinout, with all of the pins used by the MR16 board labeled. The
MR16 is pin-for-pin compatible with all Real Time Devices’ 50-pin I/O connector boards. For these boards, all of
the unlabeled pins on the MR16 carry the same signal found at the I/O connector of the interface board you are
using.
If you want to access other signals on your interface board, such as analog inputs and timer/counters, you can
connect to the 16 signals available on TB3 at the top of the MR16 board. This terminal strip is labeled with the pin
numbers brought out to it from the 50-pin connector. To find the signals available on these pins, refer to the interface board’s pinout.
To further expand the number of relays you can control using your digital I/O lines, you can use the daisy chain
connector on the MR16 board, P2. The signals at this connector are identical to the pinout of your 50-pin interface
board. You can connect to another MR16 (each digital output line will now control two relays, one on each MR16
board), or to a TB50 or XB50 breakout board to easily access all of the interface board signals. Our technical staff
will gladly help you select the accessories you need for your application.

Connecting to a 40-pin A/D Converter Board
The MR16 can be adapted for use with all Real Time Devices’ 40-pin interface boards by making I/O connections using an RTD Discrete Wire Kit. Available with single or twisted pair wiring, this kit is designed so that you
can mate connectors with otherwise incompatible pinouts. Using Figure 4 and the pinout diagram for your interface
board, you can make the appropriate connections.
Connecting to the Signal Sources
One digital output line from the A/D interface board is required to control each relay. These lines are labeled
DIN0 through DIN15 on the MR16 P1 connector pinout because they are inputs to the MR16 board. These lines are
programmed through the A/D interface board. When selecting normally open operation of a relay, the relay is open
when the control line is low and closed when the control line is high. In normally closed operation, the relay is
closed when the control line is low and open when the control line is high. When the relay is energized, its LED
status indicator light will be on. The MR16 cannot be controlled by analog lines! If your interface board’s digital I/O
is provided by an 8255 programmable peripheral interface (PPI), then you must set up the lines that you use for the
MR16 as mode 0 outputs. The interface board manual tells you how to set up the PPI.
TB1 and TB2 are 25-terminal miniature screw terminal strips which let you easily connect and disconnect the
relay outputs to external devices. When operating the relay as a normally open switch (open = low and closed =
high), connect the external device the relay is controlling to the NO terminal screw and the ground to the COM
terminal screw for the selected channel. When operating the relay as a normally closed switch (closed = low and
open = high), connect the external device to the NC terminal screw and the ground to the COM screw terminal. An
additional ground terminal is provided on each strip for your convenience when making these connections. Figure 5
shows a diagram of the channel 1 (DIN0) relay circuit.
